A process for producing an optically active 3-azide-carboxylic acid ester by reacting an optically active 3-hydroxycarboxylic acid ester and a thionyl halide in the presence of a basic substance in an organic solvent to produce an optically active 3-halogenocarboxylic acid ester which is then reacted with an azide salt represented by the formula: MN
3
(wherein M is an alkaline metal) in water or a mixture of water and a water soluble organic solvent.
通过在有机溶剂中,在碱性物质存在下,将光学活性的3-羟基
